ps the fuji f30 can take iso 1600 shots with no noticeable noise…
That is not completely true. Small compact cameras with their small sensors produce loads of noise even at lower ISO speeds such as 200–400 already. The Fuji compacts are indeed known to handle this pretty well, but still produce lots of noise at ISO 1600. Even My Canon 40D dSLR does generate noise at that high a speed.
What is true though is that you will be looking for the fastest lens possible (lowest f. number) and a camera with well known high ISO speeds. Another HUGE factor would be getting a camera with image stabilisation, like some Canons with IS or some Nikons with VR (same thing). That will let you shoot more stable in low light conditions. Good luck!
